摘要(Abstract)：

目的 建立气相色谱法测定氟比洛芬酯中的1-氯乙基乙酸酯。方法 使用DB-1毛细管色谱柱（30 m×0.32 mm,1.0μm），升温程序：起始温度为80℃，维持2 min，以5℃·min-1的速率升至100℃，维持4 min。FID检测器温度：250℃；进样口温度：200℃；载气：高纯氮气，载气流速：1 mL·min^(-1)，进样量为1μL。结果 1-氯乙基乙酸酯在0.61～9.08μg·mL(-1)，进样量为1μL。结果 1-氯乙基乙酸酯在0.61～9.08μg·mL^(-1)范围内，回归方程为y=0.919x+0.046 7(r=0.999 4)。1-氯乙基乙酸酯的回收率在98.89%～109.35%之间，平均回收率为102.8%(RSD为3.4%)。精密度、定量限、检测限、溶液稳定性、耐用性经验证，结果均良好。1-氯乙基乙酸酯为制备氟比洛芬酯的中间体，精制前的氟比洛芬酯中，1-氯乙基乙酸酯的含量远远小于限度。精制后的氟比洛芬酯，均未检出1-氯乙基乙酸酯。结论 本方法操作简便，重复性好，灵敏度高，能满足测定氟比洛芬酯中1-氯乙基乙酸酯的要求。
OBJECTIVE To establish gas chromatography method for the determination of impurity-1-chloroethyl acetate in flurbiprofen axe til.METHODS The method was performed on a capillary chromatographic column(DB-1 30 m×0.32 mm,1.00 μm).The programmed temperature was applied:The column temperature was 80 ℃(maintained for 2 min),then raised to 100 ℃(maintained for 4 min) at the rate of 5 ℃·min(-1)范围内，回归方程为y=0.919x+0.046 7(r=0.999 4)。1-氯乙基乙酸酯的回收率在98.89%～109.35%之间，平均回收率为102.8%(RSD为3.4%)。精密度、定量限、检测限、溶液稳定性、耐用性经验证，结果均良好。1-氯乙基乙酸酯为制备氟比洛芬酯的中间体，精制前的氟比洛芬酯中，1-氯乙基乙酸酯的含量远远小于限度。精制后的氟比洛芬酯，均未检出1-氯乙基乙酸酯。结论 本方法操作简便，重复性好，灵敏度高，能满足测定氟比洛芬酯中1-氯乙基乙酸酯的要求。
